I have tried the Beljum butter, and ASSOS, and Chamois Butt'r. After reading this thread last year, I gave nubutte chamois butter a try. It far outperformed everything else. I didn't need to slather it on, I didn't have to reapply after 4 hours of cycling, and it washed off very easily (both me and my short :-) ). I will never go back to anything else. It supports Junior Cyclists, it is distributed locally here in Boulder, CO. I am just blown away by the quality of the product. Two Thumbs up!
